Next-Generation Security Tools

Security policy includes what you are securing - include assumptions (like physical security: "we assume that the building is secured against unauthorized entry").

"Attack surface" - lots or little ports listening, what they do, etc

Some switches revert to hubs when they get overloaded - switched networks aren't safer. (But we knew that already, ettercap.)

NSA has OS security guidelines on their site.

Sample intrusion policy for us:

  • PCs
  • research group servers
  • core servers
  • sysadmin staff workstations

Hard disk encryption

  • Pointsec (Win32)
  • Mobile Armour (Win32, Linux, maybe Mac OS X)
  • people had bad experiences with PGP Disk
  • File Vault - ambivalent
  • Built in Windows agent is ok, but uses escrow by default - and it's the local admin, unless you change it

Problems with passphrases: sometimes they get truncated "silently"
